SPECIFICATION formngpart of Letters Iatent No. 749,577, dated January 12, 1904. Application led September 15, 1903. Serial No. 173,279. (No model.)

To a/Z whom t may concern,.-

Be it known that I, EDMUND OGUMPAGH, a citizen of the United States, residing at Rochester, in the county of Monroe and State of 5 New York, have invented certain new and useful Improvements in Stamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- 1o pertains to make and use the same.

My invention relates to improvements in stamps, especially those designed for stamping checks.

The object of my invention is to produce a 15 simple, cheap, and easily-operated stamp, one that shall be attractive in appearance, capable of easy adjustment, and not likely to get out of order.

With these objects in view my invention o consists in the construction and combination of parts, as hereinafter described and claimed.

In `the accompanying drawings, Figure 1 represents a perspective View of my improved stamp, and Fig. 2 a cross-section of the same.

` 2 5 t represents a rectangular base provided with a ledge To this ledge are attached spring-clips c, which serve to hold the casing d of the stamp in proper position upon the base. The casing Z may be readily detached 3o from the base, however', for the purpose of `re-inking the roller or for inspection.

e represents a shaft passing through the casing carrying the cyllnderf, on which 1s mounted the type-wheel g. This type-wheel carries.

` `4 5 chine-which arms are pivoted on a rod Z, running through the machine and screwed into the same, as shown at 1.

The rod Z is provided with a projecting portion 2 bent over at right angles to the main rod, (shown in dotted lines in Fig. 2,) which 5o affords a handle by means of which the rod Z may be unscrewed and slipped out of the casj ing, thereby allowing the inking-roller and its supports to be easily removed.

Centrally mounted in the front of the cas- 5 5 ing is a hollow screw 3, provided with a knurled head 4. This hollow screw receives the end of a spiral spring 5, one end of which is kept in position by said hollow screw and the other end of which is mounted on a pin 6, 6o projecting forward from the strip j, the pin 5 being `located exactly in the center of said strip. By turning the screw 3 the tension of the spring 5 will be varied, thereby varying the pressure with which the inking-roller 7L is 65 held up against the typewheel.

The front part of the casing is curved, as shown at m, and at thc center of the rear part there is an extension n, in which is carried the plunger for giving the downward blow, 7o which drives the check or other piece of paper against the type. The part n is perforated and through it passes a plunger-rod o, provided with a hand-wheel p, and `surrounding the rod is a spring q, which bears against a 75 projection just below the hand-wheel and a projection (not shown) inside the extension w.

To the lower part ot' the plunger is attached a horizontal piston fr, provided with a groove,

s, in which is mounted a strip of elastic mate- 8O rial t, preferably rubber.

A screw d is mounted in the back portion of the extension t and serves to limit the downward motion of the piston r when the handwheel 2) is forced down. whereby a lighter or 8 5 heavier embossing cfect may be produced on the check or other piece oi' paper.

The open top of the casing d is closed by a plate e, removably secured thereto, preferably by screws. The rear central portion of 90 this plate is cut away, so that it can iit closely around the extension a. The plate o is provided with a slot w, through which the portion t of the piston passes when it is desired to stamp a check. Onthe shaft e, outside the 9 5 casing, is carried the index-wheel m, carrying numbers arranged from 5 up, although of course all the numbers are not given on this Patent of the United States, is-

A stamp comprising a base with spring-clips thereon, a casing open at the bottom adapted to engage said clips and provided with an eX- tension and with an opening in its top, aplateprovided with a longitudinal slot covering said opening, a type-wheel revolubly mounted in said casing, an indicator-wheel connected to said type-wheel so as to move therewith, an inkingroller adapted to contact with said typewheel, supports for said roller consisting of a horizontal strip provided with eXtensions,ver

tical arms, and a removable rod on which said arms are pivotally mounted, said strip being provided with a projecting pin in its center, a hollow screw passing through the front of said casing, a spiral spring engaging said pin and said hollow screw,a plunger provided with a strip of yielding material on its lower face, a rod supporting said plunger and mounted in a perforation in said eXtension,a spring encircling said rod, a hand-wheel adapted to be struck by the user, and a screw adjustably mojinted in said extension beneath said handwheel to limit the downward movement thereof, substantially as described.

In testimony whereof I affix my signature 1n presence of two wltnesses.

EDMUND OGUMPAUGH.
